Figure. Depiction of the T. equi apicoplast genome gene arrangement, showing unidirectional coding of genes. Known
enzymes shown in red, ribosomal proteins in green, rRNA sequences in yellow, and groupings
of tRNA molecules in blue. Location of conserved hypothetical (gray), and hypothetical
(black) protein-encoding genes are shown by arrows or bars. Members of the three expanded
gene families are marked with either “*”, “¡” or “^” to indicate similar genes. The
molecule is depicted as linear, though not experimentally demonstrated to be either
circular or linear.
